groove 39 between them, the whole being pinned as at 19 to the end of the arbor.- 5A vplurality of flexible ribs 20 are mounted vabout this ,arbor 1,0, theirL opposite endsbevjing eachbent inthe form lof an'eyea's at; Y

21 and 23 Arespective`ly,see Fig. 9,. andthese upper eyes are'p'laced in this groove 391and a wire 22is passedaround thefsleevethrough these eyes thereby providing a hinge ojrpivot g joint for each rib. The opposite orlowerends f off-these ribs are also similarly -ormed with eyes as at 23 and like ,their upper ends l are-,held in an annularlgroove 40 lformed between :the notched collar 24 von 'the hub joint pintle on Vwhich theseends may swing.

This outfer` sleeve 126' is .secured 5to-:the hubf 25 by means of the screw 28. The hub 25 is mounted -to slide =longitudinally-onthe arbor l0 so that when it is moved upward or toward the fixed collarthe ribs 2O will bend outward in bow form as illustrated in Fig. 1, to receive the yarn and when moved baci; to normal, as shown in Fig. 2, these ribs set straight or parallel with the arbor thus collapsing the spindle and permitting the ball which has been wound thereon, when in expanded position, to be readily removed therefrom.

In order to provide a simple and effective loch for retaining this collar in raised position, I have formed a spring wire 29, one end 30 of which is soldered in a corresponding groove d1 in the arbor, the free end 31 of the wire being adapted to normally spring outward when released and engage the shoulder 32 of this collar thereby retaining it against the closing pressure of the resilient ribs. d hen it is desired t-o release these ribs to straighten themselves out into normal position, it is only necessary to press this wire inward, in the position illustrated in Fig. 2 and the collar readily slides down over the same.

In order to facilitate the pressing inward of this wire lock, I have irovided a separate and independent collar-shaped release member 33, which may be slid up over this wire thereby7 automatically drawing it inward to release the sliding' collar 25. rIhe stop member 3l is secured to the arbor to limit the upward movement of the sliding col lar 25.

rIhese resilient ribs may be formed of any suitable material but I preferably construct them of narrow strips of very thin spring steel so that they may be bowed readily into the desired shape.

The sleeves 18 and 2G may be provided with outwardly projecting fingers 35 on their edges, see Figs. 6, 7 and 8, so as to extend between the ribs at the joint to hold them in spaced apart relation.

One method of applying the yarn to this spindle when expanded is illustrated in Fig. 5, in which the spindle is rotated through the gears 12 and 13 and as rotated the yarn 3G is wound about it by means of a rapidly revolving iiier 37 which is rotated through the shaft 38 to wind the yarn thereonto. The spindle while rotating also receives a continuous relative movement so as to lead the yarn in any desired form onto the spindle, the preferred form being the winding of the yarn into ball form and when this bobbin is completed it is only necessary to slide the release member 33 upward, trip the latch and permit the collar 25 to slide downward and collapse the spindle, thereby permitting the bobbin del as indicated in dotted line to be readily removed therefrom and the operation repeated.

I have described one illustrative embodiment of my invention, but I desire it to be understood that the specific terms employed are used in a generic and descriptive sense and not for the purpose of lii'nitation, the scope of the invention being defined by the appended claims.

I claim:

1. A collapsible spindle comprising an arbor, a plurality of iiexible ribs arranged about said arbor, means whereby the middle portion of said ribs may be bowed outward and returned when desired, and means whereby said ribs may be retained in bowed position.

2. A collapsible spindle comprising an arbor, a plurality of flexible ribs arranged about said arbor, a collar on the arbor in which each of the opposite ends of said ribs on the arbor are mounted, means whereby one of said collars may be moved to bow the ribs outwardly, and means for releasably retainingsaid collar to hold the ribs in bowed position.

3. A collapsible spindle comprising an arbor, a plurality of iiexible ribs arranged about said arbor, a collar on the arbor in which each of the opposite ends of said ribs are pivotally mounted, means whereby one of said collars may be moved toward the other to bend outward the middle portion of said ribs into bow form, and means for releasably locking said collar in expanding position. l

et. A collapsible spindle comprising a center arbor, a plurality of flexible ribs ar ranged about said arbor', a tixed collar at one end and a slidable collar at the other end of said ribs to which collars the ends of said ribs are pivotally mounted, means for spacing said ribs about said collars, a spring lock for retaining the sliding collar when moved to expand said ribs, said lock being adapted to release said collar and permit it and the ribs to return to normal when desired.

5. A collapsible spindle comprising a center arbor, spring ribs arranged about said arbor, means for expanding the spindle by bending outward the middle portion of said ribs, means for rotating said spindle, means for winding yarn onto the expanded portion of said spindle while rotating, and means for subsequently collapsing said expanded portion to facilitate the removal of the yarn wound thereon.

In testimony whereof I aiiix my signature in presence of a witness.

GEORGE P. MACREADY.
